Fix Missing ".rtl .phpbb_alert .alert_close" RTL Pop Up Box Close Icon Margin And Float Rules

When using an RTL language, if you open a pop up box - example click the delete cookies button, the close button for the pop up box remains on the same side as it does on standard LTR languages.

This can be solved by adding a rule to the bidi.css to match the one in common.css

File:

bidi.css

Find:

.rtl .action-bar .dropdown-button-control .button {

    margin-left: 5px;

}

Add Below:

.rtl .phpbb_alert .alert_close {

    float: left;

    margin-right: 0;

    margin-left: -36px;

}
